Abstract

The invention belongs to the field of soft-hard interbedded rock mass testing, and relates to a soft-hard interbedded rock sample production device, including: a pre-pressing mold, a cutting and stacking unit and a pressing mold, and also relates to a soft-hard interbedded rock sample production device The method, using the above-mentioned device, includes the following steps: preparing a soft-layer mixed material; preparing a hard-layer mixed material; preparing a soft-layer material block and a hard-layer material block; preparing a soft-hard interlayer material block; preparing a soft-hard interlayer compressed block; Prepare soft and hard interbedded rock samples. By adjusting the distance between the load-bearing plate and the stacking port, the interlayer thickness of soft and hard interlayer materials can be easily controlled. After the soft and hard interlayer compressed blocks are solidified, they are fixed at an inclination angle to the horizontal plane, and the interlayer can be controlled by sampling with a coring machine. Inclined angle: The production process is simple and the production efficiency is high. At the same time, the single-layer material block is transported and stacked in the pre-pressing mold to ensure the integrity of the single-layer sample.

Description

technical field [0001] The invention belongs to the field of soft-hard interbedded rock mass testing, and relates to a production device and method for soft-hard interbedded rock samples. Background technique [0002] Soft-hard interbedded rock mass refers to a rock mass composed of two or more groups of rock masses with large differences in strength forming an interlayer structure. Due to the large difference in lithology between soft rock and hard rock, soft rock will develop into Weak interlayers that seriously affect the stability of surrounding rocks cause a large number of disasters to occur from time to time under the action of external geological stress, resulting in serious economic losses. Soft and hard interbedded rock mass is a kind of rock mass often encountered in the process of tunnel construction. With the continuous development of tunnel engineering, it is inevitable to pass through areas where soft and hard rock interbedded surrounding rocks such as red bed...
